Local residents might see low-flying helicopters starting next week inspecting transmission lines.
ITC Midwest announced that the aerial patrols of "high-voltage transmission structures and lines throughout its service territory" will be done from Monday, May 16, to Friday, May 27.
The areas to be surveyed include the cities of Dubuque, Asbury and Key West in Iowa and Galena, Ill. Surveying also will occur more broadly in Clayton, Delaware, Dubuque and Jackson counties in Iowa and Jo Daviess County, Ill., according to a press release.
"They include inspections of steel structures, wood poles, conductors (wires), insulators and other equipment," the release states. "Crews check for damaged or worn equipment and vegetation hazards.
"The inspection flights are often conducted at low altitudes to allow accurate visual inspection of equipment for lightning damage, wear or other potential problems."
